Cyclonephelium assamicum
Cyclonephelium? assamicum Jain et al., 1975
Now Glaphyrocysta. Originally Cyclonephelium, subsequently Cyclonephelium?, thirdly (and now) Glaphyrocysta.
Stover and Evitt, 1978, considered this to be a provisionally accepted species of Cyclonephelium.
Holotyp: Jain et al., 1975, pl.5, fig.61
Locus typicus: Assam, India; Langpar Formation,
Stratum typicum: Danian
Original diagnosis: Jain et al., 1975, p.11
Shell flat, more or less spherical, one pole (apical) mostly detached forming apical archaeopyle; surface ornamented with fibrous processes (6-10) along periphery or equator only, processes broad, spongy, proximally narrow, distally open, expanded and branched, interconnected by thin membrane, giving an appearance of thin flange around shell. Shell surface finely granular.
Dimensions:Holotype Range
Overall shell diameter 160 µm130-160µm
Body size76x52 µm75-100x50-80 µm
